Contour Enthusiasts Group Archives Forums Modifications Audio Finally Decided

I never said I have never heard of any of those companies. I have seen a shiva driver and I think everyone knows Dayton. Partexpress is where you can get most test equiptment for woofers and they sell Dayton.

I admit I am not familiar with there models, but ask them if they have a dvc, should I use just one coil and will it hurt the woofer if I do. It wont kill your woofer today, but 3 months from now when you are posting "Hey my dvc woofer with one coil hooked up died today" maybe you will remember what I said...

Using one coil would be like running a mile while breathing through a straw. Can you do it, (I cant) but most likely YES, will you die sooner YES. It is possible, we agree there, but IT will shorten a woofers life. If anyone doubts it Contact their woofer maunfacture....I don't think you can argue their rsponse.

But no company publishes the T/S parameters for each coil of a DVC driver independantly. This is your problem, you have no T/S params to enter.



I have the Dayton Loudspeaker DVC 15" at http://www.partsexpress.com/pe/showdetl...._ID=7765&DID=7. From that page, there are links to more specs and the DUMAX results. This driver also comes in a 12" version and is of the same design as the Adire Audio Shiva 12", Tempest 15", and a soon to be produced one at www.stryke.com.

The question has been asked about my particular DVC driver to the tech people where I purchased it from. As soon as I here a reply, you'll be notified, probably by Dave.

Go to http://64.37.116.230/cgi-bin/config.pl and search for 'Dayton DVC' and see what comes up.

Yes, that is where I got my drivers, #295-190.



I never said I would actually use a single coild hooked up, I'd be cheating myself out of 6dB for a 5 cent piece of wire because my amp can drive 4 ohms.

I don't think that's wuite the sam analogy, as it pertains to life expectancy. Limiting your input power (oxygen) reduces your peak performance only. Actual exercising in life tends to lengthen one's life expenctancy.

I can get the specs from one coil I have a woofer tester from parts express...

KnuKonceptz, I'm not quite finished with you yet!

I'm just a little busy right now. As soon as I get a few minutes, I'll respond!

well this was not what I wanted to start.. But it is a pretty good argument, at least I think I am beginning to understand... Somewhat..

KK,

Here is the message posted by dnewma04 at PE.

"I recently built a 7.7 cubic foot box (tuned to 20 hz) with a Dayton DVC 15. Due to amplifier constraints (only stable into 8 ohms) I am forced to just use one coil and short the other. The amp is a 300 watt mono amplifier. Is there any possibility that running only one VC will void the warranty?

Dave"


And the response by one of the techies....

"Dave ... the driver will still be under warranty.

-Paul"

I also asked my brother, who is more knowledgeable than I who quickly said, "What a waste, but you won't damage anything."

So, either the JL Audio techie doesn't know his speaker fundementals, or he just has to stand by the company's policy.

Holy crap!! This topic sure blew up!

I have to say, after reading all this I'm very impressed no one needed flame retardant boxers.

I was under the impression in the first post that the W6s were already purchased, hence the advice I gave. This obviously is not the optimum set up, but it would work. Luckily our friend has the easy option of selecting a better matched set of drivers to go with his MTX, so it's really a moot point.

I don't have any personal experience with most of the drivers you guys spoke of so I won't comment on then directly. I think whatever name is on them it really boils down to how they sound to YOU, in YOUR set up, and then of course will they hold up there.

Somebody commented that manufactures don't lie, I think. Thats relative isn't it? Ever seen a class A/B amp the size of Play station console with "400 WATTS X 4" emblazened across the heat sink?[Names withheld to protect the rediculous.] Even if it did it, what distortion %? How many channels driven? What input voltage? Load? Frequency of 1000hz, or 20hz-20000hz or more? The same can be said of speaker ratings, some are much more real world than others.

I was under the same impression that the woofers were already bought as well. Glad they werent though. Also glad that no one did do any flaming, I think we all respect each other and our views.

I totally agree with your "if YOU like it thats what matters" line. I guess it will very from maunfacture to manufacture on the voiding warranty policy (JL does it, at least appears that way) So ask them first. It will damage a speaker though, it will over work that one coil and eventually cause failure.

Also exercise will make YOU live longer, but the woofer is running on one leg, it wont finish a mile without falling....Ask the manufacture first, I guess that is what it will come to, if they keep replacing drivers then go ahead, I would not want the headache of taking out woofers and also not haveing them perform to there optimum level.

I'm sure it does depend a lot on the speaker's design. Are the coils 2", 3", even 4"? How many layers? Is the wire round, or edge wound? Cooling provisions, etc. etc..

As you know though, dvc was created for flexability sake, not because svc wasn't strong enough to do the job.

Any whooo. It's good talking to you guys...civily.

btw. Aren't one of you guys in OH.?
